l SPECIFICATION forming part'of Letters Patent No. 768,556, dated August 23, 19`04.

Application tiled May 23, 1903.

T0 @ZZ whom] it may concer-n.:

Be it known that I, VICTOR BLANGER, of Seaview, in the town of Marshfield, in the county of Plymouth and State .of Massachusetts, have invented certain new andl useful Improvements in Spindles, of which the following is a specication This invention has relation tospinningmachinery, and more particularly to spindles and spindle-driving mechanism, having for its object certain improvements by means of which the spindle may ybedriven at a high rate of speed without increasing the speed of rotation of the usual driving-drum commonly, employed in such mechanism.

On the drawings, Figure 1 represents one Fig. Qrepresents a plan view of thesame. Fig. 3 represents in plan view another embodiment-.of the invention in whichk a single Vband or tape is employed for driving a plurality of spindles.

Referring to the drawings,`the spindle-blade grooved member 0; subthe whirl hitherto used. The spindle base or bearing et is secured to the spindle-rail b by awasher co3 and a nut c, screwed on the threaded portion of the spindle base or bearing. In lieu of passing the tape, cord, or band, which is driven by the drum, around the whirl on the spindle it is passed around a grooved pulley c, which is shown as journaled on an upright stud-shaft d, arranged in parallelism with the` axis of the spindle-blade a.' The shaft l is mounted upon the end of a swinging arm e, which is to an upright stud f, rising from an'eXtenslon C05 on the spindle-base a2. These parts are-shown somewhat conventionally; but it will be understoodfthat provision is made for lubricating them. The stud f is parallel to the stud-shaft d and to the blade a.

Secured tothe pulley c there is a relatively large wheel g', vwhich is shown as shod with leather, rubber, rawhide, or other suitable frictional material, as at g. The periphery of the shoe is'complemental to the groove in stantially similar to arm or -lever e, as shown in Fig. 2, is curved and 1s of such length that when the member l g is in contact with the member a a line passserin No. 158,473. (No man;

l ing throughthe axes of the shaft d and the spindle a will be substantially parallel to` a line at right angles to the drum, (not shown,) but the location of which i'sindicated bythe driving band or cord z..

It is to be observed that the pulley c and the driving member g are located in front of the spindle, so that the tension of the band/L `is such as to draw the member g' into firm rictional contact` with the member ct ony the spindle-blade a. To assist, however, in holding the two members of the couple of rotation-to wit, the members g and adin contact, there is aspring i, one end of which bears against the arm e and the other end or which is inserted in the aperture in the spindle-base, as shown in Fig. 2.

In virtue of the construction as thus described the spindle is driven at an accelerated speed much greater than if the band L-were passed around the usual whirl on the spindle.

In Fig. 3 a construction is shown in which ya single driving member is utilized for effecting the rotation of two separate spindles. In this instance the arm e is pivoted, to one spindie-base, so that the member g, carried thereby, is adapted to make contact with the two driven members a on the twoy spindle-blades o a. The spindle'to which the arm is not pivoted is adjustable toward and from the other, as usual in spinning-frames, so that it is possible to insure a firm frictional'contactof the member g with both the driven members a' a. of the two spindles. Y A

I do not herein claim speciiically the construction shown in Fig. 3, in which a single band is employed for effecting the' actuation of two spindles. f

Having thus explained the nature of the invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what 1 claim isbelt-driven pulley mounted on the free end of said arm, and a couple of rotation comprising a relatively large wheel connected to the belt-driven pulley and a relatively-small wh'eel IOO connected to the spindle, said wheels being` in frictional Contact, whereby tbe speed of the belt-driven pulley is multiplied in transmission to the spindle.

2. The combination of a spindle base or bearing, a blade journaled therein and having,1 a rotary driven member fast thereon, lan arm pivoted to said base or bearing' on an axis parallel to the spindle, a belt-driven rotary member mounted on the free end of said arm, and a friction member fast to said belt-driven member and in operative Contact with the driven member on the spindle-blade.

3. The combination of a spindle, an arm pivoted on an aXis parallel to said spindle, a belt-driven pulley mounted on the free end oi vieron BLANeIcn.
